NORWALK, 01-110, A CORPORATION OF OHIO PAPER DELIVERY MECHANISMApplication filed September 15, 1930. Serial No. 481,871.

This invention relates to mechanism, for use in conjunction with anymachine delivering a continuous web of paper, and is adapted to lay suchpaper back and forth in a fan 5 fold in a suitable receptacle, fortransportation, storage or subsequent use. In large printing plants, itfrequently results that printing presses or other machines deliver acontinuous web of paper at a time or location where it is not feasibleto utilize the same in some machine which is to act subsequentlythereon, as for instance a machine which may cause registering printingor may fold the previous product. Accordingly, it is necessary totransport or temporarily store the product of the first machine.

My mechanism accomplishes the desired result very eficiently, byproviding a simple device which takes the web of paper as it isdelivered from the first machine and folds it back and forth in asuitable container which may be used for purposes of storage ortransportation. The invention is illustrated in the drawings hereof andis hereinafter more fully described and its essential novel featuressummarized in the claims.

In the drawings, Fig. 1 is a sectional side elevation of one embodimentof my invention; Fig. 2 is a vertical sectional view thereof in a planeat right angles to Fig. 1, looking from the right hand edge of Fig. 1.

As shown in the drawings, A. indicates a suitable web of paper which iscontinuously delivered by any suitable machine which has acted thereon,such machine being indicated conventionally by the pair of coactingdelivery rolls 10 and 11. My mechanism takes this web and folds it backand forth into the position indicated at A1 in a suitable crate or othercontainer 20 which may serve to store it or transport it.

As shown in the drawings, I have provided a continuously rotating drumover which the web of paper extends. This drum is shown as suspended inbrackets 31 and 32 depending from the ceiling of the room. The drum isrotated in timed relation with the machine delivering the web. To thisend I have shown a belt 35 passing over a pulley 12 on the originalmachine and thence over a is a rock arm 58.

pulley 37 on the shaft 38 of the drum 30.

The pulleys 12 and 37 bear the same relation toeach other as do theperipheries of the rolls 11 and 30, which makes the peripheral speed ofthe drum 3O equivalent to the speed of delivery of the web A to thedrum.

40 and 41 designate a'pair of standards suitably supported and extendingto a region adjacent the drum 30. In this region the standards carry apair of aligned studs 42 and 43 projecting toward each other, on whichis journalled, between the standards, a swinging hollow guide 50 whichhas side plates converging from a comparatively wide mouth at thepivoted end to. a narrow discharge slot at the swinging end.

As shown, the two side plates, designated 51 and 52, are cut away toformlight gratings, and these plates at their ends join end members 53and 54 which extend upwardly in position to be journalled on the studs42 and 43. The end member 54 is journalled directly on the stud 43carried by the standard 41, while the end member 53 carries rigidly withit a short sleeve 55 journalled on the stud 42. Rigidly mounted on thesleeve By means of this arm, the guiding device may be rocked back andforth as indicated by the broken lines 50 and thecurved arrow X inFig.1.

To rock the hollow guide in'c'onformity' with the peripheral speed ofthe drum 30, I provide a pulley 60 on a short shaft 61 carried by thestandard 31, this pulley being connected by a belt 62 with a pulley 63on the shaft 38 of the drum. On the shaft 51 of the pulley 60 is a crank65 which is connected by a pitman 66 with the rock arm 58. The distancebetween the effective crank arm 65, from the axis of the pulley 60 tothe point of attachment of the pitman, is less than the effective arm 58from the axis of oscillation of the hollow guide to the point ofattachment ofthe pitman. Accordingly, as the crank 65 revolves, the arm58 is oscillated back and forth, giving the hollow guide the swingingmovement indicated by the broken lines in Fig. 1.

To vary the length of the stroke of the folded strip of the desiredlength, I provide several openings in the crank 65 and the arm 58,enabling the pivotal attachment of the pitman at any one of severalpoints on either the crank or the arm.

It is important that the rate of swinging of the hollow guide beadjusted with reference to the speed of the delivery of the web of paperA, so that the product may be taken care of as fast as fed, and to thatend I make the pulleys 60 and 63 adjustable in effective periphery, sothat the speed of revolution of the crank 65 may be variedavithreference to the rotation of the drum 30. As shown, cause this variableperiphery by making each pulley 60 and 63in the'form of apair of cones,as illustrated in Fig. 2, one of the cones of each pulley beingadjustable toward or from its mate. This movement of a cone may be made,for instance, by the nut 69 screwing onto the rotatable shaft 61 or asimilar nut 39 onthe shaft 38. The belt 62 is of such form that it mayoccupy a different radial position in the pulley according to the adjustment of it, as illustrated by the relative positions of this belt inthe pulleys 60 and 63 in Fig. 2. Accordingly, by loosening the cones ofone of the pulleys and tightening the other, the ratio of thesepulleysmay be changed, and thus the pulley 60 may be caused to rotatematerially faster or materially slower than the pulley 63, as desired.

By means of the adjustments described, I am able to cause the hollowguide to swing back and forth for the desired distance in proper timedrelation to the peripheral speed of the drum 30, so that the guide willlay the web of paper back and forth in thereceptacle 20, in folds of thedesired length as fast as received.

My device is very simple in construction and readily installed for usewith existing machinery delivering a web of paper and is adapted toreceive such paper as fast as delivered and fold in a continuous backand forth fold of any desired length. When thus folded in the receptacle20, the material is in very convenient form to be transported to someother machine, or stored temporarily until its use is required, and thenit may be fed directly from the receptacle 20 to the subsequently actingmachine.

I claim:

1. The combination of a rotary drum over which a web of paper may pass,means for rotating it, a hollow guide pivotally mounted adjacent thedrum having a comparatively wide entrance mouth and a discharge mouth,standards pivotally supporting the guide, a rock arm on the guide, apulley rotatably connected with the drum, a crank driven by the pulley,and a pitman connecting the crank and rock arm.

2. The combination of a rotary drum over which a web of paper may pass,an oscillatory guide for the paper pivotally supported adjacent thedrum, a rock arm for oscillating the guide, a pulley adj ustablyconnected with the drum to rotate at variable speeds with referencethereto, a crank on the pulley, a pitman connecting the crank with therock arm andmeans for adjusting the points of connection of the pitmanwith the crank or rock arm, or both.

3. The combination of a rotary drum over which a Web of paper may pass,a pivotally mounted guide adapted to receive the paper from the drum, areceptacle adjacent the mouth of the guide, means for rocking the guideback and forth, including a pulley on the drum and a pulley connectedtherewith by a beit, said pulleys being adjustable todifferent effectiverelative diameters.

In testimony whereof, I hereunto affix my signature. 7 V
